These files are based on the master branch (the patch was based on it too, though shader files in master are virtually identical with 0.43.0 release files), so it's... not a good idea to install them onto a build of OpenMW with AnyOldName3's shadows pushed. Unless it isn't one.

Looks like what was packaged up, is in a 'Fog Shaders' directory. It's important to move the shader files in Fog Shaders/resources/shaders to the resources/shaders subdirectory of your OpenMW installation.

If there is interest, I can try and see if I can get this to work with the Shadows branch too. However, with that still in flux, keeping that up to date moment to moment may be difficult. I would almost rather wait until the shadows work is finalized and then rebase this patch.
